Comparison of HT Concomitant With RT vs RT Alone in Patients With a Detectable PSA After Prostatectomy

Phase 2

Active, not recruiting

• Conditions: Adenocarcinoma of Prostate
• Interventions: Drug: Degarelix; Radiation: Pelvic Radiotherapy

• Registration Number: NCT01994239
• Lead Sponsor: UNICANCER

Brief Summary

The purpose of this study is to select the best therapeutic strategy in studying the effectiveness of the association of a short duration hormonal therapy and radiotherapy compared with radiotherapy alone, in patients with a detectable PSA after radical prostatectomy.

Detailed Description

Study the effectiveness of the association of a short duration hormonal therapy by degarelix (Firmagon ®) and radiotherapy, with radiotherapy alone on survival without events in the treatment of detectable PSA after radical prostatectomy.

122 patients should be included over a period of 2 years. Patients will be treated according to the following scheme:

* Arm A (61 patients) : Pelvic Radiotherapy: 46 Gy and prostate only boost up to 66 Gy

* Arm B (61 patients) : Arm A + hormonal therapy by degarelix during 6 months

Primary Outcome Measures

Name	Time	Method
The efficacy of the combination of hormonal therapy by degarelix and radiotherapy on event-free survival	5 years

Secondary Outcome Measures

Name	Time	Method
Survival without clinical event	5 years	The clinical recurrence will be defined by the discovery of a local recurrence in rectal examination, the appearance of metastases by imaging or biopsy, or clinical manifestation associated with malignant disease without elevated PSA but with histological documentation or imaging.
kinetics of testosterone	up to 12 months after the end of the radiotherapy and after biological release
Overall survival	5 years
Patient Quality of life	up to 5 years after the end of the radiotherapy	QLQ-C30, QLQ-PR25 and IPSS
Survival without biological event	5 years	Biochemical recurrence was defined as a PSA \> nadir + 0.4 ng / mL confirmed by a second PSA\> nadir + 0.4 ng / mL in elevation.
